Structure describing the visual appearance of a single stereo layer
struct FLayerDesc
uint32
Flags
Uses LAYER_FLAG_...  See: ELayerFlags.
uint32
Id
The layer's ID.
FIntPoint
LayerSize
Size of texture that the compositor should allocate. Unnecessary if Texture is provided. The compositor will allocate a cubemap whose faces are of LayerSize if ShapeType is CubemapLayer.
FTextureRHIRef
LeftTexture
Texture mapped for left eye (if one texture provided, mono assumed)
ELayerType
PositionType
Which space the layer is locked within.
int32
Priority
Render order priority, higher priority render on top of lower priority. Face-Locked layers are rendered on top of other layer types regardless of priority.
FVector2D
QuadSize
Size of rendered quad.
FTextureRHIRef
Texture
Texture mapped for right eye (if one texture provided, mono assumed)
FTransform
Transform
View space transform.
FBox2D
UVRect
UVs of rendered quad in UE units.
